We recently discovered that an Exchange Server could not accept any (external) messages anymore due to low disk space. It is the Exchange "Back Pressure" feature that caused the Exchange Server to stop sending emails.
Now using a tool I found that there are many log files (.log) in directory:
C:\Program Files\Microsoft\Exchange Server\V14\Mailbox\Mailbox Database <id>\
These log files take up several GBs and thus all my resources (disk space), causing my problem.
I had that specific directory open for a few minutes and it was updating and adding logs. To me it looks like it logs every incoming (?)/outgoing (?) email.
- Is it safe to manually delete these mailbox database .log files or should this be done by an Exchange tool?
- How can I control this logging? (enable/disable/auto-cleanup/... settings?)
- What exactly does such a mailbox database .log file contain?
Thanks in advance.
